Of the customers interviewed, 430 said they were not interested in either product, 270 were interested in the first product, and 400 were interested in the second product. What percentage of the total customers interviewed were interested in both products? (A) 10% (B) 15% (C) 20% (D) 25% (E) 30% The Fibonacci sequence is often used to illustrate sequences defined by recurrence, that is, sequences in which a term can be determined based on knowledge of previous terms. In the case of the Fibonacci sequence, we write Tn + 2 = Tn + 1 + Tn, and thus, any term can be obtained by knowing the two previous terms. Considering the above, determine the term T2021 of the Fibonacci sequence, knowing that T2018 = m and T2020 = p. (A) p + m/2 (B) p - m/2 (C) p + 2m (D) 2p - m (E) 2m - 2p J modeled a math problem using an exponential function of the form a(x)=1000e^kx, and L, working on the same problem, arrived at the modeling b(x)=10^2x+3. Assuming that both modeled the problem correctly, and that ln x = loge x, what is the value of k? (A) ln 2 (B) ln 3 (C) ln 10 (D) ln 30 (E) ln 100 The bisection method is an algorithm used to find approximations of the roots of an equation. You start with an interval [a,b], which contains a root, and, at each step of the algorithm, you reduce the interval by half, using a theorem to determine whether the root is to the left or right of the midpoint of the previous interval. That is, after step 1, you obtain an interval of length b - a/2; after step 2, you obtain an interval of length b - a/4; and after step n, you obtain an interval of length n b - a/2. This process continues until the obtained interval has a length smaller than the desired maximum error for the approximation. To apply this method to the interval [1,5], how many steps will be necessary to obtain an interval of length smaller than 10^-3? (A) 9 (B) 10 (C) 11 (D) 12 (E) 13 A store sells a product in two types of packaging: single (with one unit of the product) and double (with two units of the product). In a certain month, 16 double and 20 single packages were sold, generating revenue for the store of R$488.00. The following month, 30 double and 25 single packages were sold, generating revenue of R$790.00. What percentage discount was given on each unit of the product when purchasing the double package? (A) 5% (B) 8% (C) 10% (D) 12% (E) 15% ____________________________________________ 00:00 Welcome 00:50 Before starting an advertising campaign, a bank conducted a survey, interviewing 1,000 of its customers. 04:50 The Fibonacci sequence is often used to exemplify sequences defined by recurrence. 08:17 J modeled a math problem using an exponential function of the type a(x)=1000e^kx, and L. 14:26 The bisection method is an algorithm used to find approximations of the roots of an equation. 18:52 A store sells a product in two types of packaging: unitary (with one unit of the product) and single-unit (with one unit of the product). 25:40 Full BB course in the description.
